Mindray MEC-1000 Patient Monitor Mainboard Motherboard 5100-20-268

Mindray MEC-1000 patient monitor mainboard 5100-20-2687

► Mindray MEC-1000 patient monitor mainboard 5100-20-2687 brief introduction

The Mindray MEC-1000 patient monitor motherboard is the central circuit board that controls the operation and functions of the patient monitor. It is responsible for processing and interpreting data from various sensors and modules to display vital signs and other patient information on the monitor screen. The motherboard also controls communication between different components of the patient monitor, such as the display, keyboard, power supply, and other modules. It is an important component to ensure smooth and accurate operation of the patient monitor.

► Functions of main control part

As the core part of the whole system, it finishes the following functions:

1) control, management and scheduling of parameter measurement part, recorder and keyboard;

2) display drive of TFT screen, STN screen and CRT screen;

3) 3-way expansion serial port realized by FPGA;

4) alarm given for system fault;

5) storage of RTC, hardware WatchDog and relevant parameters

► Introduction to principle

The main control module is the central part of the system and includes serial ports, TFT display interfaces, and CRT display interfaces to each module. The BDM interface is reserved on the board for software debugging or downloading.

• CPU system

The CPU is the main component of the main control module. Connect peripheral modules through buses and I/Os to complete data communication, data processing, and logic control.

• real time clock

RTC (Real Time Clock) provides time (hours, minutes, seconds) and date (year, month, day) information. RTC information can be changed by the CPU.

• FPGA and VRAM

VRAM is used to store display data. The CPU sends display data to the VRAM via the FPGA. The data in VRAM is a mapping of the actual display device.

FPGAs have various extended serial ports that can communicate with external parameter parts.

The CPU writes the collected data to his FPGA, which sends it to the external parameters section.

• watchdog

After powering on, the watchdog provides a reset signal to his CPU, FPGA, and Ethernet controller.

Provides Waterdog timer output and voltage monitoring functionality.
